There was a problem hiding this comment. What about There was a problem hiding this comment. @johnstcn I wasn't aware that people could access the coder registry that way. How does this work? Can people self-host our registry? There was a problem hiding this comment. As I write this, I realise that prefix-checking won't even help here unless we attempt to parse the module as an URL and extract only the hostname. In any case, I don't see any reason that someone sufficiently motiviated couldn't do this if they controlled the domain It's more of a contrived hypothetical though and I'm not going to block on this! There was a problem hiding this comment. I think it's acceptable to misclassify a small percentage of modules. With telemetry, we’re more focused on aggregates, and cases like this are unlikely to affect the overall picture. |
